I just changed the argument to some of the ntsec functions to take a
mode_t* rather than a int*.  The reason for this is that I changed
mode_t to an unsigned value from a signed value and mode_t types were
being passed to these functions in some situations.  unsigned is more
consistent with linux and more in keeping with the way that the value is
used.

I am hoping that, since I didn't receive any warnings about unsigned
comparisons, everything is ok but I thought I'd better send out a
heads up to Corinna and Pierre anyway.

I also moved the control of the ufoo_t and foo_t typedefs to
include/cygwin/type.h and protected everything with ifndefs.
